Replace square by the correct number in each of the follwing: (i) (2)/(7)=(8)/(square) (ii) (3)/(5)=(square)/(35) (iii) (5)/(8)=(20)/(square) (iv) (45)/(60)=(9)/(square) (v) (40)/(56)=(square)/(7) (vi) (42)/(54)=(7)/(square)

In figure XY|| seg AC. If 2AX=3BX and XY=9 , complete the activity to find the value of AC. Activity: 2AX=3BX :.(AX)/(BX)=(square)/(square) :.(AX+BX)/(BX)=(square+square)/(square) .........(By componendo) :.(AB)/(BX)=(square)/(square) .............1 DeltaBCA~DeltaBYX .......( square test of similarity) :.(BA)/(BX)=(AC)/(XY) ..............(Corresponding sides of similar triangles) :.(square)/(square)=(AC)/9 :.AC=square ...........[From 1]

Write the proper number in the empty boxes : 25/8=(25xxsquare)/(8xx125)=(square)/1000=square

The regression equation of x on y is 40x-18y = 214… (i) The regression equation of y on x is 8x -10y +66 =0….. (ii) Solving equations i and ii, barx=square bary=square :. b_(yx) = (square)/(square) :. b_(xy) = (square)/(square) :. r = square

The regression equation of y on x is 2x-5y +60 =0. Mean of x = 18 :. bary=square sigma_x:sigma_y=3:2 :. b_(yx)= (square)/(square) :. r = square

Write the correct number in the given boxes from the following A.P. -3,-8, -13, -18 ,….. Here, t_(1) = square, t_(2) = square, t_(3)=square, t_(4)=square, t_(2)-t_(1) =square, t_(3)-t_(2)=square therefore a =square, d=square

Replace square in each of the following by the correct number :(a) 2/7=8/square (b) 5/8=10/square (c) 3/5=square/20 (d) 45/60=15/square (e) 18/24=square/4

Complete the following activities. Write the correct number in the given boxes from the following A.P. 1,8, 15, 22,….. Here a = square, t_(1)=square,t_(2)=square, t_(3)=square ,…… t_(2)-t_(1) = square- square =square t_(3)-t_(2) = square -square = square therefore d=square

Write the correct number in the given boxes from the following A.P. 3,6,9,12,……. Here t_(1)=square, t_(2)=square, t_(3)=square, t_(4)=square, t_(2)-t_(1) = square, t_(3)-t_(2) = square therefore d=square

fill in the boxes with the correct symbol >, (8)/(8) square (2)/(2)
